SH1、Y-1對(duì)蘋(píng)果生長(zhǎng)結(jié)果及其生理特性的影響

矮化密植具有優(yōu)質(zhì)高效、結(jié)果早等優(yōu)點(diǎn),已成當(dāng)今蘋(píng)果生產(chǎn)的必然趨勢(shì)。本試驗(yàn)以SH1和Y-1為中間砧,八棱海棠(Malus robusta Rehd.)為基砧的’長(zhǎng)富2號(hào)’(Malus domesticaBorkh.cv.Nagano Fuji No.2)蘋(píng)果樹(shù)為試材,研究不同中間砧對(duì)樹(shù)體的生長(zhǎng)結(jié)果特性、葉片組織結(jié)構(gòu)、光合特性、碳氮代謝和果實(shí)品質(zhì)的影響,為生產(chǎn)上SH1和Y-1的選擇利用提供理論依據(jù)。主要研究結(jié)果如下:1.與SH1矮化中間砧相比,Y-1樹(shù)體長(zhǎng)勢(shì)緩和,更有利于富士蘋(píng)果矮化,有利于當(dāng)年生新梢形成花芽,以Y-1作矮化中間砧的蘋(píng)果樹(shù)新梢長(zhǎng)度極顯著低于SH1矮化中間砧蘋(píng)果樹(shù),短枝率(64.43%)顯著高于SH1樹(shù)體(44.45%),長(zhǎng)枝比例(10.50%)顯著低于SH1樹(shù)體(19.21%),秋梢節(jié)間長(zhǎng)度顯著短于SH1,短80.51%,葉片厚度和比葉重高于SH1樹(shù)體,但差異不顯著。2.花后80 d前,Y-1的葉綠素含量和凈光合速率顯著低于SH1,花后80 d以后,Y-1極顯著高于SH1。花后60d,Y-1的Fv/Fm、ΦPS Ⅱ和ETR極顯著低于SH1,光飽和點(diǎn)低于SH1,補(bǔ)償點(diǎn)高于SH1...
